Figs. 1. 5, 6 and 7, show the various positioiis of the valve. which correspond to the the operati "positions of lever.

With reterence to the drawings any device comprises in substance a hollow body nortion V f at top end bottom thercol for its said hodv in the liuesaid body in the present instance hei 153 shown with th i threaded into the ton Qas hur said cod? 1 in own tr pe. nee is of dV 1% formed in apered valve conical valve 5 e tending v UIVQTG positions of oi: the valve a threade I gerniitted to flow through nasa-ge 6 of the body portion.

o therethrough from end. to end lateral 'nunicates with the pas- ,7 *ided at each end all counterhore 8 and respectively adapted to receive screws 10 and 11 said screw 10 functioning to retain said vs -e within the body portion 1. and th intcroosed between the head C') channel 7 which co 5, and there oi the sci w and the said body portion washer which adapted to slide freely on the face of the body portion to perinlt free rotation of the valve therein.

Extending radially from the channel to the periphery of the valve is a channel the A end oi? which is adapted to register with channel 14 extending upwardly through the top oi: the body portion 1 and aid latter channel 1 lis adapted to erm u continuous part of a channel 15 ihich extends upwardly through a braclaiet support 16. which latter is attached to the l portion. 1 and held in place by dihp 17. which extends around the of the ateral p rtion of? the hody led outer end l 1 and which las its ends held together to cause the said strap to grip the hody meniv" means of screw 18.

At the top ot' the oracket L6 is rotatably mounted a star wheel of well known form which has u*-'ed hereto a tooth or corrucjat said and wheel heing carried by :1 spindle Mil /d in a no; 22 oi the hir cltet. while established in second is 93 v the top the hraclzet and occupya suitable ecess formed therein is a nie e of flint 24 which is adapted to hear the neriohery of the toothed wheel 20. so that when the latter is rotated, a spark is formed in well lIDOWU manner.- The mid his; 5% has laterally threaded extenwhich the said recess or ch the flint 24- is established, ids: and can 26 is threaded to said u and confines within said extension and hetwecn the rear end of the flint and the hc-.d the said cap a spring (not shown which exerts a pressure tending to Force the said (lint forwardly against the Pivotally mounted at the forward end of the horizontal portion of the body 1 is an operating member 30, said n'iember comprising an arm 31' which constitutes the opcrating lever of the device, andan extension 32 which is adapted to engage a pivotally mounted and substantially hook-shaped e ment carried by a second member pivotally secured by means of the said screw 11 between the n'iember and the ii'orward face of the body portion 1. The said member 534 con'iprises a rear-weirdly extending arm which attached to the end there of one end of, a coileo. spring 36. the other end of said spring beim' sect .Cl to the rearward extension 37 of the spindle 21. which carries the star wheel 19, said spring 36 tending to retain the said member 34; in a given normal position. as shown in Fig. 1.

The central portion of the arm 31 is pressed outwardly to form a laterally extending arm 38 upon the member 30 and thls arm 38 has secured to the end thereof one end. of spring 89, the other end of which spring is secured in suitable manner to the said extension 37 of the spindle 21.. said spring 39 exerting force upon the c arm tending to retain the arm 81 in an elevated position and the member 30 in the posltlon shown in F 1.

The said element 33 is pivoted at n to the member and normally tends to assume the position shown in Fig. 1, with the forward end thereof lving down in front of the extension 32 (if the member 30, so that when the arm 31 is moved downwardly to rotate the member 30 in a counter-clockwise direction. (see Fiat 1), the said extension 32 which occupies the same plane as the element 33 engages the inner edge of said element and carries the said member 3 1 forwardly.

The element 33 has a rearwardlyextend ing roller 42 which extends through an aperture t3 in the member 34, and which when the member 34 has been carried in the 1912121- ner previously stated in a counter-cloclrwise direction around the pivot 11, is adapted to engage the outer end of a cam extension l-l, upon the bracket 16, said cam extension preventing further downward movement of the said element 33. and as the movement of the member 341 persists, causing the said element 33 to be elevated on its pivot 41, with respect to the said member until the extension 32 of the member 30 is carried free of the lower hoolred end of the element 33. whereupon. the member 3 being released from the element 30, the spring 36 acts to return it to its original normal position shown in Fig. 1. In this rearward movement of the member 8 1, the outer edge of the element 83 rides over the outer edge of the extension. 32. which so elevates the element 33 that the rearward extension 42 is brought into engagement with one of the arms of the star wheel19, this engagement, due to the movement of the element 84, causing a partial rotation of the star wheel and of the wheel 20, and creating a spark by the friction between the wheel 20 and the aforementioned flint, this spark being formed adjacent the upper end of the channel 15, as most clearly shown in Fig. 1. 1

Upon release of the arm 31, the member 80 tends to return to the normal position shown in Fig. lunder the action of the spring 89, and when this return is made, the edge of [re extension 32 is adapted to engage an extension d5 of the element 33, and thereby to swing the said in a counter-clockwise direction. around its pivot ll to return it to the normal position in which it is shown in Fig. 1, providing it has not already returned to this position under the action of gravity. This extension 42-.5 functions particularly when the device is employed in such connection that it is required to be inverted from the position illustrated in the drawings, at which time this arrangement is necessary to return the element 33 into position to be re-engaged by the extension 32 when the i'uember 30 is again oscillated.

At the under side of the "aid member 30 is an extension &8 which turns rearwardl'y and extends across the face ofthe strap 1'7, 11:; best shown in Fig". 2, said 4-8 having a slot 49 formed therein in which is established a pin or stud 50, said stud being retained in said slot by means of a head 51 and a washer 52 secured to said stud on the inner side of the arm 48, and there being a spring 53 confined between the head 51 and the outer face of the arm L8, which spring by frictional engagement with the said arm tends to retain the saidstud against lateral movement in the slot.

The strap 17 has secured in suitable mannor as by the screw 18 to one side thereof adjacent the extension 48. a plate 1.7" which is recessed or perforated, as shown at 55 in Fig. 2, and the inner endof the stud is adapted to occupy the said recess and to be shifted laterally in the slot 4.9 by contact with the sides thereof. The said cam recess is best shown in Fig. 2, and is of general ii-shape, having in the present instance three recesses, 56, 57 and 58, at the top thereof and extending at the bottom into the point of the V. Located substantially centrally of the recess is an elevation (50. which has in. the top thereof. in the present instance, recesses 61 and 62, the point which separates the said recesses 61 and 62 rising upwardly and being disposed substantially equidistant between the two points which define the recess 57, the said outer points of the recesses 61 and 62 being similarly located respectively with regard to the recesses 56 and 5.8. When the arm 31 is carried downward, the

arm 48 is correspondingly elevated, the said stud rising upwardly along the right hand wall (see Fig. 2) of the recess 55, and finally entering the recess 56 at the top. The said recess 56 is so formed that after the stud has entered the recess to the top thereoi and the arm 81 is released, the stud in pass ing downwardly with the arm l8 will enter the recess 61 of the elevated portion 60. A further upward movement the arm. will cause the stud to enter the recess 57, which has the effect of again shifting the said stud to the left, so that when the arm e8 again moves downwardly, the stud enters the recess 62. A further upward movement or the arm l8 will bring the stud into the recess 58, which carries it to the lefthand wall, still having reference to Fig. 2, of the cam recess, and the next fOllOWiIlgI downward movement of the arm 48, the stud passing; downwardly along the said left hand wall, will permit the arm to pass down to the extreme low or normal position, as shown in the figures.

When the parts occupy the positions shown in the drawings, in Figs. 1, 2 and the stud occu ving the lower point of the recess the vali 'e 4 is in substantially the position in Fig. i, with the passage disposed laterally or" the passage 6, whereby the gas in t e pipe 2 is prevented from passing; upwardly to the burner 3. When the arm 31. is moved downwardly to the extreme low position, the said stud will occupy the recess and in this position of the lever 31, the Valve 4: occupies the position illustrated in Fig. 5, with the passage 5 in alignment with the passage 6, whereby is permitted to flow upwardly to the burner. In this position of the alve, also, the channel 13 is carr ed in a substantially vertical position so that the upper end thereof registers with the lower end of the channel 14 whereby is permitted to flow throurgh the channels 7 and 13. and through the channcl 15 to the top or the bracket 16. In the downward movement of the arm 3i to bring the valve into this latter position, the element is released from the projection 32,

in the manner previously described, just after the valve is brou 'ht into position to open the passages permitting; the flow of gas through the channel 15 and to the burner so that the spark generated. as previously described, by the rotation of the star vheel w ll have the eilect oi? igniting the ll wing trom the top of the channel thus 1 a pilot 1 which in turn will i e the flowing trom the burner 3.

l DOn release of the 3 the spring ms to turn. the member in a. clockwise erection, this movement being limited by e stud entering the recess 61 in the eleion 60, and in this condition the val as shown in Fig. 6, permitting t tree flow of to the burner. The valve, how ever, has moved sufficiently to carry the channel 13 out of coincidence with the channel l-l. thereby cuttni oil the pilot light an i the flow of to the channel 15.

It now it is desired to make the light dim, a turther downward movement of the arm By in carr *ing the arm 31 downwardly and ,.-ie:?.sin it, the parts are returned to the position hown in ig. 1, in which case again shuts of the dew of to the burner.

in order to eliminate-as tar as possible the jar d ie to the springc back or the mei the val-re her si ter release from the member 30, at the of said member 34 a p 65, the lower end of which arm the member springs haclrwardly to as its normal position. strikes against the side of the arm 48, which is the moment in an elevated. positon, the ar oi the contact being broken by the action of the spring 6! I also provide upon the cord or chain 66 which is attached to the arm 81 and by means of which the device is actuated, a linlrj 67 which is interposed between the upper end of the chain 66 and the arm 81, said linlr comprising a hollow cylinder 68 he established therein a plunger 69 with 11 extending downwardly through the ottom or" said cylinder and attaching to the chain 66, said cylinder 68 being secured to the end of the arm 31 by means 01' a suitable link 70. Confined between the bottom of the cylinder 68 and the under side of the plunger 69 is a spring Tl, through vvl chain is trausn ittod to the a rm 3 l. This dee further relieves the shock due to the w 1 contact of the member 34: with the arm in the manner specified. I

One big advantage of the desribed construction is the fact that l am able to keep the lighting; device well away from the burner or nmntle, since the pilot light may be projected to a considerable distance, and there is as a consequense no possibility of damage to the apparatus from the heat of the burner. I am. for similar reasons, en-

abled to pro 5: a lighting device of stainlm i w *7 1- q are. (,OflStlUCtlOlz which MltllOllL alteration may be applied to any kind of fixture. it will further be noted. that the outer mechanism oi? the d vice is detachable from the body 1, and that as consequence the said body may be employed, with possible modifications of the mechanism, to suit particuar conditions of it will be apparent recess may U8 h spring the pull upon the varied as by, elimination of the recess 62, which. would do away with the low light 'oirovision, and still other modifications are possible Within the scope of the invention.
